उत्तर

Assertion is wrong statement but reason is correct statement.

Explanation:

The silver mirror test can be used to determine Tollen's. \[\ce{[Ag(NH2)2]+ OH-}\]. Only aldehydes, not ketones, react with Tollen's reagent to create silver.

A silver mirror test is not given with this affirmative test.

The carbonyl group is present in both aldehyde and ketone.
